This invention relates to railway rolling stock and more particularly to certain improvements in locomotive tenders for Stoker fired locomotives, and it also appertains to improvements in a Stoker fuel conveyor for use with such an improved tender.

It is the principal object of this invention to construct a tender for stoker fired locomotives, the tender conveying unit being driven from its forward end and the locomotive unit of the Stoker being driven from its rearward end, such driving means arranged to be received in the conventional compartment usually provided for this purpose and being disposed wholly below the fuel bin oor and the shovelling deck of the tender.

In carrying out the principal object of this invention, the adjacent ends of the Stoker conveying system are offset laterally and vertically in a manner to reduce the vertical distance between the two conveying sections. Such lateral disposal of these sections, necessitates in certain cases, that the axis of the conveyor which underlies the fuel bin be offset laterally from the longitudinal center line of the tender, and accordingly, this forms another object of this invention.

These and other objects of this invention will become apparent as the following description is read in connection with the accompanying drawings in which Figure 1 is a central vertical longitudinal section through the tender conveying unit of a stoker as applied to locomotive tenders;

Figure 2 is a section taken on the line 2--2 of Figure 1;

Figure 3 is a section taken on the line 3 3 of Figure 1;

Figure 4 is a section taken on the line 4 4 of Figure l;

Figure 5 is a section taken on the line 5-5 of Figure 4; and

Figure 6 is a View similar to Figure 2 showing a modified form of the invention.

On the drawings, the tender is indicated by A, and comprises the water compartment W and the fuel bin F which is mounted above the floor I, the forward continuation of which constitutes the shovelling deck I I. The floor I6 is apertured as at I2 and a plurality of shiftable plates I3 control the size of the aperture whereby varying amounts of fuel may be fed from the bin F into the trough I4 mounted beneath the fuel bin oor IB. The trough I4 is disposed within the water compartment W and is supported from the base frame I5 by the legs such as I 6. At its forward end, the trough `I4 extends from within the water compartment into an alcove l1 which is separated from the water compartment W by the rear wall I8 and the side walls I8a and Ib, formed integral with the trough I4. While the construction thus far described has emphasized the fact that the trough I4 is disposed within the water compartment, the present invention is not limited to use with the trough so disposed but is capable of advantageous use in such instances where a front drive for the stoker trough is desired.

A conveyor screw I9 is mounted in the trough I4 and is driven from its forward end by suitable gearing housed in the gear case 20. This gearing comprises a pinion 2i, which is driven from any suitable source through the coupling member 22 (Figure 4) and meshes with a gear 23 mounted on a shaft 24 which is in driving connection with the conveyor screw I9. The screw I9 urges fuel forwardly past the Crusher 25 which reduces the fuel to a size suitable for firing. The crushed fuel then drops into the conduit 26 which is disposed below the trough I4 and laterally thereof. A chute 2l connects the forward end portion of the trough I 4 and the conduit 26. While the conduit 26 is shown as being formed integral with the trough I4, obviously, it could also be made as a separable unit rigidly attached to the base frame I5 of the tender.

Mounted in the conduit 26 is a conveyor Screw 28 which is connected universally as at 29 to the screw 3D housed in the tubular section 3|. The tubular section 3l is flexibly connected as at 32 to the forward end of the conduit 26 and leads forwardly to the locomotive for delivering fuel into the firebox. As the rear of the conduit 26 is a gear case 33 which houses a gear 34 mounted on an extension of the screw 28 whereby motion is transmitted thereto. The gear 34 is meshed by a pinion 35 mounted on a jack Shaft 36 which underlies the forward portion of. the trough I4 and extends into the gear case 20. A gear 31 is mounted on the opposite end of the jack shaft 36 and is driven by the gear 23, thereby completing the train of gears for operating the screws I9 and 28. It will be observed from the drawings that by offsetting the conduit 26 laterally below the trough I4, the gearing for driving the stoker screws is compactly disposed within the limits of the compartment or alcove I'I` Usually, the locomotive unit of the Stoker, termed the discharge conduit is disposed on the longitudinal center line of the locomotive and tender, and it has been customary to similarly dispose the remaining connected conduits of the conveying system. This being necessary so that there will not be an initial angularity between these conduits when the locomotive and tender are on a straight track. It will be readily understood that if the conduits where disposed angularly when on a Ystraight track, this condition would be greatly aggravated when the locomotive and tender are negotiating curves. Such a condition would result in rapid wear upon the conduit joints due to the strains and stress imposed thereupon and would necessitate a frequent renewal of these parts.

Accordingly, since the conduit 26 is disposed laterally of the trough l, I prefer that the axis of this conduit remain on the longitudinal center line of the locomotive and tender, and instead I dispose the axis of the trough lll to the right or left of this center line, as the case may be, a distance equal to the lateral offset between the conduit 26 and the trough i4. The aperture i2, is likewise offset and the side slope sheets M and 4| of the fuel bin are preferably terminated at the marginal edge of this aperture, thereby forming a fuel bin which is self cleaning.

On Figure 6, which illustrates a modified form of the invention, the axis of. the trough Ita.' is disposed on the longitudinal center line of the tender, while the axis of the conduit 26a is offset laterally therefrom. Such a construction can be used advantageously in those instances where the tubular section leading from the tender is connected to the discharge conduit at a point offset laterally from the vcenter line of the locomotive, or, in such cases where rail curves are so slight that an initial angularity of the conduits is not objectionable. In all its otherV details, this form of the invention is similar to the preferred form.

While I have illustrated and described two forms of my invention, I contemplate the use `of my invention to the extent of, offsetting each of the conduits ld and 25 from the center line of the locomotive and tender. Structures of such scope I have included within the terms of the following claims.
